Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to “ride” under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
Information
The side and/or curtain air bags may
inflate when the vehicle is rolled over
by a side impact collision, if the vehi-
cle is equipped with side and/or cur-
tain air bags.

Warning and indicator lights
Information
Make sure that all warning lights are
OFF after starting the vehicle. If any
light is still ON, this indicates a situa-
tion that needs attention.
Ready Indicator
This indicator illuminates :
When the vehicle is ready to be driven.

When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, we recommend
that you have your vehicle inspected
by a HYUNDAI authorised repairer.
Service Warning Light
This warning light illuminates :
When the POWER button is in the ON position.
- It illuminates for approximately 3seconds and then goes off.
When there is a problem with relat- ed parts of the electric vehicle con-
trol system, such as sensors, etc.
When the warning light illuminates
whilst driving, or does not go OFF
after starting the vehicle, we recom-
mend that you have your vehicle
inspected by a HYUNDAI authorised
repairer.

System malfunction
Check FCA (Forward Collision
Avoidance Asst.)
When the FCA is not working prop-erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case, we
recommend you to have the vehicle
inspected by a HYUNDAI autho-
rised repairer.
The FCA warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
OAE058246L
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
unintentonally activate. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message will not be
displayed.
(Continued)
WARNING (Continued)
If there is a malfunction with the
FCA system, the Forward
Collision-avoidance Assist is
not applied even though the
braking system is operating
normally.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.(Continued)

Limitations of the system
The Forward Collision-avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a pedes-
trian in the roadway through radar sig-
nals and camera recognition to warn
the driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
(Continued)
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates only
to detect vehicles or pedestri-
ans in front of the vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the opposite
lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot detect
the driver approaching the side
view of a parked vehicle (for
example on a dead end street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
